Application filed May 7, 1907. Serial No. 372,361.

To all whom it may concern:

Be it known that 1, JAMES A. RAIFORD, citizen of the United States, residing at C0- lumbus, in the county of Muscogee and State of Georgia, have invented certain new and useful Improvements in Plow-Stocks, of which the following is a specification.

The present invention relates to certain new and useful improvements in the construction of plows, and more particularly to a plow stock embodying novel means for attaching the plow point thereto.

The invention also contemplates the provision of a scraper mounted upon the stock in the rear of the low point to facilitate spreading of the dirt oosened thereby.

To this end the invention consists essentially in a plow stock having a transverse opening formed in the lower portion thereof, and a plate extending through the opening, one end of the plate being extended upwardly to form a shoulder engaging the plow point while the opposite end of the late is extended downwardly and carries a s oulder engaging the scraper.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a perspective view of a plow embodying the invention. Fig. 2 is an enlarged vertical sectional view through the lower portion of the stock. Fig. 3is a detail view of the plate for retainingthe plow point and scraper in position. Fig. 4 is a detail view showing the manner of attaching the handle. Fig. 5 is a detail view showing a modified method of attaching the stock to the plow beam.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Specifically describing the present embodiment of the invention the numeral 1 designates the plow beam provided at its forward end with the usual clevis 2 while its rear end is curved downwardly to a slight extent and has the handle carrying frame 3 attached thereto. This frame comprises a pair of bars having their lower ends secured to the beam 1 upon opposite sides thereof, while their upper ends are diverged outwardly and have their extremities returned upon themselves to form the clamp 4 receiving the handle bar 5 provided at its extremities with the laterally extending and curved handle pieces 6. It will thus be apparent that when the clamps 4 are loosened the handle bar 5 can be turned to throw, thehandle pieces 6 at the desired angle and they can be rigidly held in this position by again tightening the clamps. A brace 7 is also provided for the handle, the upper end thereof carrying a clamp 4 cooperating with the before mentioned clamps 4, while the lower end is adjustably connected to the plow beam by means of a bolt or pin.8

passing through a selected one of a series of.

openings 27, thus admitting of the handle carrying frame 3 being raised and lowered.

The' low stock 9'is preferably formed of a single ength of material which is doubled upon itself, a loop or opening 10 being formed at the lower end of the stock, while the ends of the strip at the upper extremity of the stock embrace the beam 1 and are connected thereto by means of abolt 11 passing throughadjusted and the plow point caused to produ'ce a deep or a shallow furrow as desired. A suitable brace 12 is employed, one endthereof being connected to an intermediate portion of the plow stock, while the opposite end is connected to the beam 1. A plate 14 extendsv through the o ening 10 at the lower end of the stock and as the forward portion thereof extended upwardly as indicated at 1.5 to form a shoulder abutting against the upper edgeof the plow oint 16 to prevent turning of the latter. twill also be observed that the upwardly extending portion 15 of the plate carries rearwardly extending flanges 17 at its extremities which embrace opposite sides of the stock. The rear portion of the plate 14 is extended downwardly at 18 and fits against the scraper 19 mounted upon the back of the stock. The scraper 19 and plow point 16 are both held in position by means of the bolt 20 which extends through the opening 10 and also passes through a perforation in the downwardly extending portion 18 of the plate 14. Laterally projecting flanges 2O are formed in conjunction with the upper portion of the member 18, the upper ends of the flanges carrying rearward projections 22 engaging the top of the scraper to prevent turning of the latter upon the bolt 20. Rearwardly extending flanges 23 which embrace the plow stock are formed upon the lower portion of the downwardly extended portion 18 of the plate 14. In the specific construction of the scraper 19 it will be observed that the same projects laterally upon opposite sides of the stock, the projecting portions of the sera er having their lower edges inclined upwardl y and serving to spread the earth loosened by the low point.

A slight modi 'cation is shown in Fig. 5 in which the upper end of the stock is extended forwardly at 24 and provided with a collar 25 receiving the plow beam and designed to be clamped in position thereon by means of a set screw 26. Where this construction is employed the lower edge of the plow beam is preferably provided with a series of teeth constituting a rack and the forwardly bent end 24 of the stock is also referably provided with teeth for engaging t e rack. This construction admits of the upper end of the stock being readily clamped in any desired position upon the plow beam so as to hold the plow point at the required inclination.

Having thus described the invention, what is claimed as new is:

1. In a plow, the combination of a stock having an opening formed therein, a plate positioned within the opening, a plowpoint mounted upon one side of the stock, and a laterally disposed scraper mounted upon the opposite side of the stock, the before mentioned plate being provided at one end with a shoulder engaging the plow point and at the opposite end with a lateral extension fitting against the scraper and engaging an edge of the same.

2. In a plow, the combination of a stock having an opening formed therein, a plate positioned within the opening, a plow point mounted upon one side of the stock, and a laterally disposed scraper mounted upon the opposite side of the stock, the before mentioned plate being provided at one end with a shoulder designed to engage the plow point while the opposite end is extended downwardly and is designed to fit against the scraper, the said downwardly extending portion of the plate being provided with lateral flanges carrying projections engaging an edge of the scraper.

3. In a plow, the combination of a stock having an opening formed therein, a plate positioned within the opening, a plow point mounted upon one side of the stock, and a laterally disposed scraper mounted upon the opposite side of the stock, the before mentioned plate being provided at one end with a shoulder designed to engage the plow point while the opposite end is extended. downwardly to fit against the scraper, the downwardly extending portion of the plate carrying rearwardly extending flanges enibracing the stock and also being provided with laterally extending fl anges formed with projections designed to engage an edge of the scraper.

4. In a plow, the combination of a stock having an opening formed therein, a plate positioned within the opening and having a shoulder at one end thereof and projections at the opposite end, a plow point mounted upon the stock and engaging the shoulder, and a scraper mounted upon the stock and engaging the projections.

5. In a plow, the combination of a stock having an opening formed therein, a plate positioned within the opening, and having one end thereof extended upwardly to form a shoulder while the opposite end is extended downwardly and provided with pro jections, a plow point mounted upon the stock and engaging the shoulder, and a scraper mounted upon the stock and engaging the projections.

In testimony whereof I afiix my signature in presence of two witnesses.

JAMES A. RAIFORD.
